Improvement in horseshoe-calks



YJOSEPH JOREY, or NORTH MANCHESTER, CONNEQTICUTa 12mm Patent No. 91,237, dated June 15, 1869.

IMPROVEMENT IN HORSESHOE-CALKS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom fit ma/y concern.- I y Be it known that I, JOSEPH J oREY, of North Manchester, county of Hartford,and State of Connecticut, have invented certain new and useful Improvements in the Manufacture of Horseshoe-Calls; and, to ena- ,ble' others skilled in the art to make and use the same, I will proceed to describe, reference being had to the drawings,'in which the same letters indicate like parts in each of the figures.

The nature of this invention consists' in enveloping apiece of steel in a bar of iron, from which the calk ,is formed, yso thatthe calk, when formed, will have a steel centre or point surrounded with iron, the object of which is to surround or embody the steel point in iron, so that, as the steel wearsaway, the iron, being softer thanV the steel, willv wear away faster, and thus keep the calk sharp, or in good working-order, and thereby less liable to break than when all made of steel, cheaper, and more durable for use.A

In the accompanying drawings are shown this improved oalk, and the blank from which they are formed.

a is a blank, prepared after my invention, from which the calkis swaged, and a steel-point centre, surrounded with iron, is produced.

ov are two calks, swaged into shape from a blank, a.

d are dowels, formed at the base ofthe calk, for the purpose of securing said calk to the shoe, by means of insert-ing the dowel into au orifice and riveting, or by a screw-thread, formed on the dowel, fitted closely into a threaded orifice in the shoe, and, by means of Aa nut-formation at the base of the calk, is closely and' firmly secured in the shoe.

I first take a bar of iron, about iv-eighths of an inch in diameter, and drive a punch nearly through sult I propose to secure by swaging-dies, formed of the` proper or desired shape, so that a uniform size and shape may be secured, and the calks rapidly produced.

It will thus be seen that I am enabled to produce a self-sharpening calk, having all the advantages of an all-steel calk, and the further advantage of.A an iron base and dowel, while the calk kproper is surrounded.l

by the iron, which wears aw'ay around the point faster than the point itself, and rendering itself-sharpening, thus avoiding the liability of breakage experienced in the useof the all-steel calksand, at the sameV time, secure a better and cheaper article of manufacture,

rtrade, and use.

I believe I have thus shown the nature, construetion,vand advantage, so as to 'enable others skilled'in the art to make and use the same therefrom.

Vhat I claim, therefore, and desire to secure by The herein-described horseshoe-calk, with steely point and core, constructed from the blank a, in the manner and for the purposeset forth. JOSEPH JOREY.
